What is generator fuel injection pump?

Diesel injection pumps are engineered to deliver precise amounts of fluid into reservoirs or production systems, and are frequently utilized in generators to pump fuel into engine cylinders. Jet pumps, which are a type of positive displacement pump, operate on the principle of expanding and contracting chambers to transport fluid.

The fuel injection pump of the BISON generator is an integral part of its operation. This critical component plays an important role in ensuring generators operate at optimum efficiency while maintaining reliable power output and reducing emissions.

Engine Fuel Injection Pump

How the generator fuel injection pump works

The fuel injection pump is responsible for delivering precise amounts of fuel into the combustion chamber of a generator’s engine. It operates under high pressure, made possible by a complex mechanism involving several key components:

  • Plunger: Creates high pressure.
  • Delivery Valve: Controls the delivery of fuel.
  • Injector Nozzle: Atomizes the fuel for better combustion.
  • Governor: Regulates the amount of fuel depending on load demand.

These components work together to ensure that the right amount of fuel is delivered at the right time, resulting in efficient combustion and power generation.

Impact of Fuel Injection Pumps on Generator Performance

A well-functioning fuel injection pump directly impacts the generator’s performance and reliability. Proper fuel injection leads to efficient combustion, which results in consistent power output and prevents engine damage.

Fuel injection pumps contribute significantly to fuel efficiency. Precise control of fuel delivery allows for optimal combustion, reducing wastage and saving costs.

Emission control is a critical concern in power generation. A well-regulated fuel injection system can minimize harmful emissions by ensuring complete and clean combustion.

generator fuel injection pump Buyer's Guide

Purchasing a fuel pump for a BISON diesel generator can occasionally seem overwhelming and perplexing. Manufacturers of diesel generator parts are committed to simplifying this process as much as possible. BISON strives to address any queries you might have while searching for the appropriate fuel pump for your diesel generator.

The importance of fuel injection pumps

Engine fuel injection pumps significantly contribute to the engine’s performance, fuel efficiency, and emission levels. They provide an accurate and precise supply of fuel to the engine, ensuring optimal combustion and thus, better engine performance.

By regulating the amount of fuel delivered to the engine based on its current requirements, fuel injection pumps help improve fuel efficiency. This means the engine only uses the necessary amount of fuel, reducing waste and saving costs.

Moreover, by ensuring a fine and evenly distributed fuel spray, fuel injection pumps help achieve a more complete combustion process, reducing harmful emissions and contributing to a cleaner environment.

An incorrect fuel injection pump can cause immediate problems such as erratic running, power loss, or even failure to start. In the long run, it can lead to inefficient fuel consumption, increased emission levels, premature wear and tear on engine components, and an overall reduced lifespan of your generator.

types of fuel injection pumps

China BISON’s diesel generator operation relies heavily on fuel injection pumps, as they ensure that the right amount of fuel is supplied to the engine when needed. These injection pumps come in a variety of forms, each with its own advantages, disadvantages, and appropriate uses.

Mechanical Fuel Injection Pumps

These fuel injection pumps use purely mechanical elements such as gears, levers and springs to meter and deliver fuel. Fuel delivery is timed based on engine RPM and load conditions.

Advantages: Mechanical pumps are typically durable, reliable, and require less maintenance. They’re also less susceptible to electrical failures.

Drawbacks: Their efficiency and precision are not on par with their electronic counterparts, potentially resulting in increased fuel usage and emissions.

electronic fuel injection pumps (EFI)

EFI systems use sensors and electronic controls to determine the exact amount of fuel to be injected at any given moment, improving fuel efficiency and reducing emissions.

Advantages: EFI pumps offer better fuel economy, improved performance, and lower emissions compared to mechanical pumps. They also provide more accurate fuel control, which can extend engine life.

Disadvantages: They are more complex and expensive than mechanical pumps. They also require a power source and can be prone to electrical issues.

common rail fuel injection pumps

This system separates the functions of fuel pressurization and injection. A high-pressure pump pressurizes the fuel, which is stored in a ‘common rail’ and available to all injectors. The injectors, controlled electronically, then inject the fuel into the cylinders.

Advantages: Common rail systems provide even greater control over fuel injection, leading to improved efficiency, performance, and emissions control. They also allow for multiple injections per cycle, which can reduce engine noise.

Choosing the right fuel injection pump depends on a number of factors, including the type and size of the generator, the intended use, and the operating environment. For example, a mechanical pump may be preferred for smaller, less complex systems or harsh environments where reliability is critical. On the other hand, an EFI or common rail system may be more appropriate for larger generators or for applications where fuel efficiency and emissions control are major considerations. It is always best to consult with a BISON generator specialist to determine the best solution for your specific needs.

What should consider when buying a generator fuel injection pump?

When buying a fuel injection pump for your BISON generator, there are numerous aspects to take into account. Choosing the correct pump can significantly enhance your generator’s performance and efficiency. China BISON will assist you in identifying the crucial characteristics to consider during your purchase.

Flow Rate

The rate at which the fuel is delivered to the engine through the fuel injection pump is known as the flow rate. It is quantified in gallons per minute (GPM). Ensuring a higher flow rate means that your generator will have sufficient fuel to function at its optimal capacity. For instance, the BSION High-Flow engine fuel injection pump offers a high flow rate, ensuring your generator gets ample fuel supply.


The pressure of a fuel injection pump refers to the force exerted to deliver fuel from the pump to the engine. A pump with higher pressure can deliver fuel more efficiently, leading to better generator performance. 

Horsepower Rating

The horsepower rating of a fuel injection pump should match your generator’s engine capacity. A mismatch might lead to inefficiency and possible damage. China BISON Fuel Injection Pumps come in a range of horsepower ratings to suit various generator sizes.
